The new Learjet 75 Liberty is a modern light cabin jet, with the performance to sling shot from runway to final approach for all but the longest and most distant trips. However, as important as speed and range are to such a cabin, they aren't the key differences that will make this Learjet model more desirable than its predecessors, the 60 and 40.
Instead, it is something completely different and new that will make this jet more desirable to those who crave speed as well as luxury: a smooth ride.
It's not just the cabin air that will seem smoother in the Liberty either; there are key differences in design that represent a leap forward for Learjet, which had previously struggled with control harmony and buffet-free handling.
The wing alone represents an enormous leap forward over the Learjet 40 series , to say nothing of the 60 models. The reason is that it's a new design altogether, one that was actually conceived by manufacturing partners in China for Bombardier aircraft (specifically the long-range Global 5000 and 6000 series). After Bombardier successfully completed test flights in Quebec, a similar wing was then deemed ideal for use on the new Learjet 75. The result is one of the most advanced wings ever to be placed on a light cabin jet .
Specifically, it's not so much about aerodynamic design, but construction. The new wing is built using a carbon composite/aluminum hybrid material, which makes it both lighter and stronger than most current wings. Moreover, the thin yet rigid leading edge characteristic of the wings on Bombardier aircraft has been duplicated for use in the 75. This feature not only allows for effortless control response at high speeds, but also reduces the drag that is normally produced by a thick wing's drooped leading edge. The 75's wing places the cabin further back from the engines than on previous models, thus allowing for tremendous noise reduction.
